Sam, I used to do maintenance on a Vital Industries "Squeeze Zoom"
video effects generator that had a three phase 208 VAC input, 5 VDC 1000
Amp power supply, plus several other supplies. It powered a full six
foot rack of boards to do digital video effects to NTSC video for a TV
broadcast control room. It was full of 4K X 1 1000ns ram, and ran with
a Z80B processor to do real time video effects. What a monster! Almost
one full card cage of memory boards to get 768 K of memory to store two
fields of video and chroma information. I'm glad I don't have to mess
with it anymore.
Of course, a couple hundred amps at 10 volts is enough to start your
car engine on cold mornings.
